SAFETY GATE.

Application filed October 24, 1921, Serial No. 509,940. Renewed October8, 1926.

This invention relates to a safety gate for highways, railway crossingsand the like, and is particularly designed and adapted for use inconnection with motor vehicle highways where the ordinary crossing gatedoes not afford suflicient resistance or obstruction to the passage of avehicle to protect the vehlcle and its occupants or to prevent them frompassing the gate when it is down or closed. The invention consists inthe novel construction, combination and arrangement of the severalparts.

In the accompanying drawing, Flg. 11s an elevation of a safety gateconstructed 1n accordance with this invention; and Fig. 2 1s a plan viewpartly in section of the gate.

In carrying out this invention, supports or standards 31 are solidlyerected or disposed at the sides of a roadway for crossing a railway, orat any other place where it is desired to erect a barrier or gate, andthese standards extend considerably above the height of a vehicle. Atthe inner sides of the standards are spaced vertical supports 32 whichconstitute guides for channels 33 attached to a rigid gate 34. This gateis preferably in the form of a U-shaped structure opening away from arailway track 1 and with the slldes 33 secured tothe outside of theextremities of the gate. v

Extending between the extremities of the U-shaped structure are aplurallty of cables 35 of flexible material preferably connected bycross pieces 37 and forming a flexible barrier. The extremities of thecables extend over rollers 36 carried by the extremities of the gatemember 34 and the extremities of the cables are connected by extensiblecoil springs 38 to the opposite side of the gate structure.

On the inner side of the gate 34 is a projecting bumper or buffer 45normally pressed outwardly by springs 46. It is obvious that when thegate is lowered the first impact of a vehicle, with the cables 35, whichform a yielding barrier extends the springs 38, and if the vehicle isnot stopped thereby, it will next engage the bumper 45 compressing theconvolute springs 46. This further cushions the impact of a vehicle withthe cross member 34 which can not be passed without wrecking the gate orthe side supporting structure.

At each end of the gate is attached a raising cable 39 which extendsover a Winding drum 40, and on another portion of the winding drum iswound a cable 41 attached to a counterweight 42. This winding drum isoperated through a train of gears 43 by an electric motor 44.

In order to control the raising and lowermg of the gate, the motors 44at the opposite ends are wired in parallel to work in unison, and switchclosing devices 47 and 48 may be provided on opposite sides of theroadway and connected by conductors 49 and 53 for controlling themagnets 50 and 54 to operate solenoids 51 to which switch arms 52 areconnected for controlling the supply of current to the motors, thesource of which may be within the switch devices 47 and 48.

It is obvious that when this gate is lowered into position it willconstitute both a gradual stop and a final barrier to prevent thepassage of a vehicle, and to prevent its entering upon the tracks of arailway beyond it. While the invention is particularly designed andintended for railway safety gate, it is obvious that it may have a moregeneral use wherever applicable. I

I claim:

1 A railway crossing gate comprising a rigid cross member with sideextensions at the front, and a yielding buffer comprising flexiblemembers yieldingly mounted at the outer ends of the extensions.

2. In a gate of the class described, a U shaped gate member and aplurality of cables yieldingly mounted across the extremities of thegate member.

3. In a gate of the class described, a U- shapcd ralsable structure, aplurality of cables resiliently mounted across the U- shaped extremitiesof the structure, and resilient means within the structure for furtheropposinga yielding impact With the cables.

. 4. In a safety gate, a rigid cross member with projecting sides, aflexible barrier mounted'in the projecting sides in advance of the crossmember, and means for mounting the barrier to yield under impact beforeengagement is made with the rigid cross member by a. vehicle.

5. In a safety gate, a rigid cross member with forward extremities atthe ends, a flexible barrier supported by the extensions in advance ofthe cross member, and resilient means tohold the barrier taut butyielding to allow the barrier to yield upon impact before the crossmember is engaged.

6. In a safety gate, a pair of side standards, a U-shaped membervertically movable 2 therein, a plurality of flexible members her withforward side extensions and chanmounted across the ends of the U-shapednels engaging the guides, means for raising member, springs attached tothe extremities of the members, and a spring pressed buffer at the innerside of the U-shapedmember to resist the final impact after theresilient members have been engaged. I 7 In a safety gate, a pair ofside standards, a rigid gate structure mounted for vertical movement inthe standards, resilient means in connection with the gate and carriedin advance of the rigid portion for opposing impact therewith,counterweighted supporting means for the gate, and a motor at each endsimultaneously operated for raising and lowering the gate.

8. In a safety gate, a rigid cross member with forward side extensions,a flexible barrier carried by the extensions in advance of the crossmember and a resilient bumper carried by the cross member to cushion animpact therewith.

9. In a safety gate, a pair of rigid side supports, a rigid cross membervertically slidable on the supports and having a for&

ward projection at each end, a flexible barrier mounted on theprojections in advance of the cross member, resilient means for holdingthe barrier taut, and a resilient bumper carried bythe cross member forengagement when the barrier is stretched a predetermined amount.

10. In a safety gate, side supports with spaced vertical guides, a rigidcross memof the cross member,

and lowering the cross member, a flexible barrier carried by theextensions in advance spring means at the ends of the cross member forholding the barrier taut, and a resilient bumper carried by the crossmember for engagement after thebarrier is engaged and stretched to apre.

determined extent.

11. A safety gate embodying in its construct-ion a barrier mounted tomovein the (liection of impact of a vehicle driven against the same, andretarding means for said barrier mounted to yield in a directionopposite from that of the movement of the barnor.

2. A safety gate embodying in its construction a barrier mounted to movein the direction of impact of a vehicle driven against the same, andresilient retarding means on opposite sides of said barrier mounted toyield in a from that of the, movement of the barrier.

13. A safety gate embodying in its construction a barrier mounted tomove in the direction of impact of a vehicle driven against the same,and coiled springs connected to the barrier on opposite sides thereofand yieldable in a direction opposite from that of the movement of thebarrier to retard said barrier.
